OSCAR E. :STOKES,' OF STREATOR, tILLINOISl BUMPER.

Application filed November 19, 1923. Serial No. 675,579.

My invention relatesto an improvement in bumpers, and more particularly to a bumper adapted for use at the front or rear end of vehicles so as to receive any impact directed against the vehicle.v

The invention has among its objects the production of a device ot the kind described which is simple, convenient, compact, du-

rable, reliable, eflicient and satisfactory for use wherever found applicable.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the Vart from the disclosures herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out inthe claims.

In the drawings, wherein like reference characters indicate like or corresponding parts: A

Fig. 1 is a top plan View of my device;

F 2 is a front elevation of the same; Fig. 3 is a sectional view taken substantially on line 3 3 of Fig. y2; and

F ig. als a rear elevation of one of the tie members.

' In the dra-wings, wherein I have illustrated the preferred embodiment of my invention, 1 indicates brackets of'any suitable or preferred construction, extending from the front or rear ends of a vehicle and designed to support and carry 4the bumper proper.

` The bumper consists ot three bars, 2 being the central ba'r and 3 and 3 being the top and bottom bars. The central bar 2 is adapted to be connectedV across .and secured adjacent its ends to the brackets 1 by means of any suitable fastening means, as ,for instance bolts Al, the ends of said bar being bent upon themselves as at 5 so as to render said ends resilient against direct pressure or thrust.

l The ends Vol the bars 3 and 3 are bent upon .themselves so as to provide elongated closed loops 6, the ends of said loops having registering apertures therethrough adapted to receive bolts 7, provided with 56 the usual heads 8. i

A tie Aor bracket member, substantially of C-shape,`has a front wall '9 and ends 10 formed rearwardly toward 4one another, these ends l0 having longitudinally extended slots 55 11 opening thereinto from fthe free ends.

The ywall 9 is formed with recesses 12 therein on the rear thereof in` registry with the slots 11 and adapted to receive the bolt heads 8 and prevent rotation of the same so that nuts 13 may be tightened in place on the bolts to hold the device assembled, in a inanner to be hereinafter described. The recesses 12 open into a central enlarged recess 14;, as shown. Y.

A strip or plate 15 is adapted to lbe clamped against the rear surface of the" ends 1t) of each tie member,said plates being pro` vided with boltholes adjacent the ends'to receive the bolts 7 and with av bolt hole intermediat'e. the end bolt holes, to receive a bolt 16 passing through the tree end'of the bar 2.

To assemble the bumper parts, the. bolts 7 are inserted through the aligned bolt holes at the inner ends ot' vthe loops 6, the lower Itar 3', then dropped into place with the bolt i'. in the vregistering slot and recess ot' the tie 'member 9, as shown more particularly ,inl F ig. then the other rod 3 is slipped into the upper end of the tie member and held in place. thereat while the rear plate 15 is slipped over the projecting freeiends vof lthe bolts 7, and the nuts 13 placed thereon and tightened to clamp the parts 9 and 15 to# gether. The ends of the ,bar 2 may be now boltedto the plate or strip 15, or,'if desired, the b ar 2 may be .already bolted to the strip bg'ore boltingsaid strip to the tie meme-r It will be noted that there' is a. space 17 provided lbetween the bars 3 and Bjand the opposed wall of the tie member so that 'i in case of any movement or play between'the two thedevice will not rattle. There is no possibility .of the bars 3 or 3 dropping or becoming displaced, even though the nuts'13 should become loose, and the parts are held clamped so that there is no rattling. Sullicient room is 'provided between the opposed surfaces of the tie member and plate` 15 Ato permit the .insertion of a wrench or other tool'to engage the head of the bolt 1G, when it is desired to tighten or loosen the same. The bumper is not only attractive in appearance, but is ot' great strength and rigidity coupled with a maximum ot resiliency. so that in case of impact the blow is cush-A ioned or eased and yet the device will not in most cases be demolished or injured or rendered inoperative.

Having thus described my invention, it is obvious lthat various immaterial modifications may be made in the same without de parting from the spirit ot my invention; hence I do not wish to be understood as limiting myself to the exact term, construction, arrangement and Combination oi parts herein shown and described or uses mentioned.
